Hypothesis: A motivational speaker claims that wearing red on the day of an exam "energizes" the brain and improves performance. Your psychology professor doubts that this is true. Design an experiment that would test whether the speaker is correct.
Independent Variable: The students who are wearing red or not. The difficulty of the exam. The room temperature of the test-taking room. The distance between the test taking facility and their homes. Time when the exam is taken. Number of students participating (100). Size of the shirts (according to their body size). Same length of the exam (2 hours)
Dependent Variable: Results of the exam, answers to different varieties of questions and difficulties.
Experiment:
10 students of the same ethnicity, the same age, and the same letter grade of the exam’s subject (SAT) will be picked for the experiment. All 100 of the students will be students that do not have tutors for sure. 50 of the 100 students will wear red, while 50 of the students will wear their choice of clothes except red. They will be given the exam and then the scores will be compared with the students who wore red. All 100 of the students will each take the same tests but with the same difficulty (SAT) in 100 separate rooms, so that they will be no instances of cheating. They will also be taking the tests where it is equidistant from their houses, so that they will not be tired coming all the way from their homes to take the test. Not only that, there will be a variety of questions that are different but with the same difficulty (SAT), so that some students are not exceptional on specific types of questions. The subjects will also be taking the tests with the same length of time: 2 hours. They will also be taking the test on the same room temperature and at the same time of the day so that their outer environment will not be the issue. The scores will be compared between the students who wore red, and students who did not wear red.
